Doctor Vlach divides all people into three groups, depending on how they would spend a lazy week's wake in the cave’yarn, having a good meal and having a bowl of biscuits«potatoes» for dessert. People from the first group — without imagination and without sense of humour — will mindlessly devote themselves to «potatoes» not till noon. People from the other — will start modelling the situation, for which someone from the guests of the cave’yarni will bombard other visitors with «potatoes». And to the third, the most numerical group can be referred to those who think about «potatoes», which fly in the wind, so much want to get up and take to realise it. Saturnin — a servant, who is easily taken to work by the narrator of this book. And the consequences are not amused.
